I have experienced accleration problems similar to those listed by others. First time, I was making a left hand turn crossing lanes of traffic and car would not accelerate when the gas pedal was pushed. It actually hesitated before taking off. Just last weekend, when pulling into the garage/driveway, I let off the gas to allow the door to finish opening and when I touched the accelerator to pull ahead, the car clunked and lurched ahead. This has happened previously on a couple of other occasions.
